The moon seems to be mostly missing, and the platform over the door is also missing a side.

Other things you may want to add if you want a really complete map are positions of the various plants and creatures, rocks and planks. I ran out of motivation before I got as far as creatures and plants in my map!

And now I've noticed a piece of terrain that I missed in my one. *sigh*

Are you saying that not everyone have 6GB ram in their machines? :P
But sure, smaller it is.

The moon and platform actually isn't any more than that. If you fly towards the side of the moon you will go straight through it, and the upper side of that "platform" is actually a part of the tower (that looks and acts like ground), not a piece of ground.

I will skip the plants for now, I can't see a good way to show them.

The community around Blueberry Garden seems pretty dead, but I hope to give it an uplift. Today with the maps. Later by releasing the tool(s) I have written, but only if Erik don't mind (just need to find a way to talk to him, and finish some things).
